In Intrexx, references can be made to any data groups. Where the output
data group and the referenced data group are both foreign data groups
from an OData connection, then a 1:1 relationship can be established
between these, provided that a corresponding relationship is defined in
the service metadata.
With a 1:1 relationship between two OData foreign data groups (OData
terminology: Entity Sets) no primary and foreign keys need to be
determined. In OData references, the relationship type is determined
and selected directly from the metadata of the OData Service.
Thus, for example, the possible relationships between a seminar and a
room booking are automatically determined by the OData Adapter from the
service metadata and made available for selection. Then click on Next.
The data fields required can be selected in the next step.
